Description
Technical field
The present invention relates to a kind of drilling machine, especially have the hand-held hammering drill machine or the hand-held drifter (Bohrhammer) of drive motor.
Background technology
This hand held electric tool or the boring bar tool that is percussive drill and rock drill form is known fully and mass selling arranged that they not only are used for the occupation needs, and are used for the needs of family expenses operation.Usually can bore body of wall, cement or stone by this hand-held drilling machine, wherein both can vertically also can flatly hole.In order to hole, use the drilling tool of so-called augers form usually, it has a scroll of extending along drilling tool and reverses groove, reverses drilling cuttings or the drilling powder of groove under will be in boring being bored by the drilling tool head by this and discharges.
When vertically or obliquely holing downwards with this drilling machine, drilling cuttings under boring in boring or drilling powder are wanted slowly to the delivery ratio drilling tool horizontal drilling of hell or when upwards vertically holing by reversing groove.This will cause: the rotary resistance that acts in boring on the drilling tool increases, and the energy consumption of boring procedure is increased.Under disadvantageous situation even can cause drilling tool stall or block in boring, under the careless situation of drilling machine operator this can cause drilling machine to rotate and therefrom handgrip throw off, often cause injury thus to the operator.
On the other hand, when other Workpiece boring of penetrating wall with this drilling machine or being made of cement or masonry, when drilling tool comes out, often cause that relatively large cement or masonry peel off around boring from wall or workpiece, this is undesirable usually.
Summary of the invention
By contrast, the advantage that has according to the drilling machine of feature of the present invention, as to have claim 1 is can avoid drill bit to stop and thus the operator being formed the danger of injury when boring downwards.By being used for the sensor of sensing drill axes orientation, can determine substantially downwards or essentially horizontally and hole, and the sensing device that is used for the rotating speed of at least one drilling running parameter of sensing such as drilling machine or torque can sense drilling machine situation at work and changes, thus, can under the situation of considering sensor signal, carry out analytical calculation, so that according to output signal analysis being calculated the motion that changes drilling tool to the sensing device output signal that indicates this situation variation.This Change Example is as being: show that when sensing device shows rotary resistance rising and sensor drill axis is vertically or during downward-sloping suddenly orientation, the analytical calculation circuit is considered as drilling cuttings or the discharge inadequate sign of drilling powder from boring with this, then temporarily closes the beater mechanism of drilling machine; Or: when sensing device is determined rotary resistance decline and sensor and is shown that boring essentially horizontally is orientated, the analytical calculation circuit is considered as the sign that drilling tool will soon pass with this from wall after boring thoroughly, the rotating speed of the drive motor of drilling machine is reduced.
Propose in a preferred configuration of the present invention: the sensor that is used for sensing drill axes orientation is a tilt sensor or is at least a so-called acceleration transducer, can identify drilling machine before the boring beginning or the orientation during holing by the analytical calculation circuit by it.
Another preferred configuration of the present invention is, the sensing device that is used for sensing boring operational factor comprises a speed probe, it obtains the transient speed of the drilling tool of drilling machine or drive motor as parameter, and it is compared with a minimum speed given in advance or a tachometer value that got access to before the short time, with the change of sensing rotating speed, this Change Example drilling tool in this way is about to the sign that stall or its just will penetrate wall at once.In order to adapt to different drilling tool diameter and workpiece material, for most of drilling machines, the rotating speed of drilling tool is adjustable, and therefore, above-mentioned predetermined minimum speed conforms with the destination and depends on the rotating speed of being set up.Perhaps also can use torque sensor, in the case, the analytical calculation device will be compared with a torque value that was sensed by this sensor before the short time by the torque that torque sensor senses with meeting the requirements.Also can imagine in principle with a torque value given in advance and compare, but this device that needs drilling machine to be useful on input or to measure the drilling tool diameter depends on this diameter very doughtily because measure torque.
Relatively, torque sensor is suitable for particularly well: determine that drilling tool is about to penetrate wall or analog at once, because the obvious decline of the drilling tool moment of resistance can take place before being about to penetrate.Compare with a torque value of before the short time, trying to achieve by drilling machine drive motor current drain or power consumption that will be relevant with drive motor instantaneous torque or conversion ground, can determine this torque decline with this torque.
The other favourable configuration of the present invention is by drawing in the further feature described in the dependent claims.

The specific embodiment
As percussive drill common on the market, housing 4 is provided with on handle member 6: a connection/stopcock 12; A regulating wheel 14 that is combined in this connection/stopcock 12, is used to regulate the rotating speed of drill bit cutting ferrule 8; A lock-button 16 and a switch that turns to 18 that is used to change drill bit cutting ferrule 8 that is used for the rig continuous service.Upside at housing 4 is provided with a slide switch 20, is used for being transformed into percussion drill operation and opposite conversion from pure boring operation.Housing 4 surrounds a drive motor and a transmission device (not shown), and in order to make motor ventilate in its side and upside is provided with ventilation slot 22.
Except that motor and transmission device, housing also surrounds: a tilt sensor 24 is used for the orientation of the drill axis of sensing drilling tool 10; A speed probe 26 is used to measure the rotating speed of the drive motor of drilling tool 10 or rig 2; And a torque sensor 28, be used for sensing and be applied to the moment of resistance on drill bit cutting ferrule and the drive motor by workpiece, in Fig. 2, only summarily express tilt sensor 24 wherein.
As the most clearly expression among Fig. 2, this tilt sensor 24 is by the housing 30 of a sealing, constitute as an ampoule made from glass, and about 1/4th of this housing is filled mercury or other conducting liquid 32.This housing 30 around an axis A rotation symmetry parallel with the drill axis B of rig 2, has a ledge 34 that shrinks gradually to male-tapered ground at it basically on the end of drill bit cutting ferrule 8.In housing 30, feed four contacts 36,38,40,42 altogether.Three contacts 36,40,42 wherein are the wire-shaped formation and are welded on like this in the wall 44 of housing 30, so that their free end extend into enclosure interior.In these three contacts 36,40,42, first contact 36 is placed on the outermost end of the ledge 34 that shrinks gradually, on the opposed facing end face 46,48 that other two are placed in housing 30, exactly these two are positioned on that adjacent side of handle member housing 30 and rig 26.The 4th contact 30 constitutes in the form of a ring, and its surrounds the inboard of taper ledge 34 and guides the outside into by the connecting line 50 in the wall 44 that is welded on housing 30.
To reach by this layout: as the drill axis B of rig 2 when with respect to the horizontal plane H is greater than the angles orientation of 45 degree with, then the first and the 4th contact 36,38 always forms by conducting liquid 30 and is electrically connected, as shown in Figure 2 the situation of 90 degree angles.On the contrary, when drill axis B tilted than 45 degree more slowly, liquid 32 flowed out and has disconnected the connection between the first and the 4th contact 36,38, the situation of 30 degree angles as shown in Figure 3 fully from outwardly directed ledge 34.On the contrary, when drill axis BA points to downwards less than the handle member 6 of the angular orientation of 15 to 20 degree and rig 2 with the angle of H with respect to the horizontal plane, then the second and the 3rd contact 40,42 always forms by conducting liquid 32 and is electrically connected, as shown in Figure 4 the situation of 0 degree angle.
As the most clearly expression among Fig. 5, four contacts 36,38,40,42 are connected with an analytical calculation circuit 52, wherein, contact 36 and 40 also is connected with a power supply 58, so that by contact 38, current signal on 42 can be determined in the analytical calculation circuit: these two pairs of contacts 36 whether, a pair of contact in 38 and 40,42 is immersed in the liquid 32 jointly, thereby provides the signal about an orientation in aforementioned two orientations of rig 2.Analytical calculation circuit 52 is connected with a control device 54 of the drive motor of rig 2, this control device can make the beater mechanism (not shown) of rig 2 turn-off or connect according to the analysis result in the analytical calculation circuit 52, and the rotating speed of drive motor is changed.
Replace above-mentioned tilt sensor 24, also can use a so-called linear acceleration sensor with a plurality of effect axles, the ball that this acceleration transducer comprises motion to be replacing conducting liquid, come these balls of sensing by suitable device with the relevant position of drill axis B orientation.
Speed probe 26 can constitute the rotating speed of the rotating speed of the drive motor of its sensing rig 2 or the output shaft of its decelerator as analog tachometer generator or as optics or electromagnetism tachometric survey device by known mode.This speed probe 26 also is connected with analytical calculation circuit 52, and this analytical calculation circuit judgement is lower than a predetermined minimum speed.But should be scheduled to minimum speed depends on the drill bit cutting ferrule of setting up 8 on regulating wheel 14 rotating speed, and the rotating speed of setting is higher, this predetermined minimum speed just heals high.Therefore be actually and determine: the rotating speed of the drill bit cutting ferrule 8 of calculating with the rotating speed of the drill bit cutting ferrule 8 measured or according to the drive motor tachometer is a side, rotating speed with the drill bit cutting ferrule 8 of setting on regulating wheel 14 is the opposing party, and this two side's ratio is lower than a predetermined minimum of a value.
Torque sensor 28 for example flows to the electric current of the drive motor of rig 2 with short time interval measurement, and this torque sensor also is connected with analytical calculation circuit 52, and this analytical calculation circuit compares the output signal of torque sensor 28 on the time period of certain weak point and can determine thus in the decline of the duration of work moment of resistance of holing.
In addition, analytical calculation circuit 52 obtains the information about the position of the switch of slide switch 20, and it also can be determined thus: it is in service or to be in percussive drilling in service that percussive drill 2 is in pure boring.
If determine in analytical calculation circuit 52: at first, contact 38 is flow through by electric current, i.e. boring downwards basically; Secondly, hanged down the measurement rotating speed of predetermined minimum speed or drill bit cutting ferrule 8 and the predetermined minimum value of the ratio of setting up rotating speed, then this indicates: drilling tool 10 impotentia is normally discharged drilling cuttings from boring.If the information of the sliding position in the case by slide switch 20 is determined: this rig is operated in service and its beater mechanism of percussion drill and connects, then a signal by analytical calculation circuit 52 temporarily turn-offs this beater mechanism and with pure boring continuation boring in service, till rotating speed is higher than predetermined minimum speed again.And carry out conversion again to percussion drill operation.Can prevent that in this way drilling tool 10 slack reaching from can prevent that thus rig 2 from rotating around drill axis B.
If determine in the analytical calculation circuit on the contrary: at first, contact 42 is flow through by electric current, i.e. essentially horizontally boring; Secondly, descend suddenly in the boring run duration moment of resistance, this can indicate: drilling tool 10 just in time penetrates workpiece also overleaf from wherein passing.In the case, analytical calculation circuit 52 makes the rotating speed of drive motor descend immediately, thus, can reduce impact energy and can stop the workpiece fragment in drilling tool 10 outlets to peel off strongly.
